CaDNAno is a software for designing DNA origami.
With the graphical interface and the built-in rules for inter-helical connections, it simplified the design process.
Since its release in 2009, caDNAno has become the most popular software in designing DNA origami.
This service converts a DNA origami in caDNAno (JSON format) to an all-atom structure in PDB format.
Here, we provide a smiley face for testing.
